The Japan Meteorological Agency recently became the billions After the introduction of the supercomputer won up to when the replacement cycle to one that is not disposed of at the price level is also one of the one thousand minutes controversy.
Such super-computer-related controversy This is not the first time. Supercomputer is time to replace every 4-5 years is noted on it once. No. 2, which are 485 billion in 2005 and 54.1 billion won in 2003 to No. 3, which are also disposed of in July 2020. The total amount collected was 78 million won.
And the introduction of Unit 5 of this month, is now also ahead of the Disposal Unit 4 have been using for 5 years.
A supercomputer to invest tens of billions of won Meteorological why you want to discard every 4-5 years, what other alternatives are looked at from CNET Korea does not.
■ glass is replaced periodically, rapid technological development and economic
Japan s Meteorological Agency has introduced the NEC SX-5 system to meteorological services dedicated supercomputer No. 1, 2000 in order to improve weather forecasts and forecast accuracy. After a supercomputer for weather Unit 2 in 2005 used the Cray X1E system of 2010, XE6 systems to No. 3.
And operating the current super computer No. 4 introduced in 2015 as a system CRAY XC40 supercomputer, Unit 5, Lenovo SD650 system introduced in 2021.
The reason for periodic replacement of a supercomputer is due to rapid technological development. It is because Shem important to save money rather appeared to have an excellent price-performance products to replace the excellent new product than using the existing product intact.
Typically is going to buy 62.8 billion won in Unit 5 started operating this month, No. 4 currently in use has a cost difference of about 78 billion to 55 billion won. But its performance is higher than 70 times the Unit 5.
With the increasing capacity by calculating the duration to increase the amount of data in accordance with the refinement and refinement of the numerical model is run into forecasts delay bound is released through the forecast time numerical model calculations are complete. Therefore periodic replacement of the supercomputer for weather are inevitable, replacing supercomputers introduction of advanced meteorological trend cycle is gradually shortened.
In addition, supercomputers are simply not used only for weather forecasting. Through the National Supercomputing Center to manage the supercomputer defense, space, disaster prevention, energy, got used in various cutting-edge scientific research and medical requirements are increasingly high levels of computational processing power.
Because of this, including South Korea, Germany, France, China and Japan, it has been operating a supercomputer to calculate the operating period of 4-5 years.
■ 1 years operating costs 60 billion, more expensive than comparable new supercomputer
Completing the mission supercomputers are mostly disposed of in the domestic as well as overseas. Because due to the technological advances being economical in terms of operating costs fell compared to the performance.
US Titan supercomputer who writes the first place, Japan Kay was also dismantled in the last 2,019 years. Kay is a super computer, a Fujitsu and RIKEN in Japan, jointly developed by the Japanese government received support. Kaku was a sequel after the current commitment of the Japanese Government No. 1 supercomputer performance 110 billion yen (about 1.2 trillion won) into the record.
According to the Meteorological Agency said in Unit 4 1 year operating costs amount to about 60 billion. This is the level 20-2500000000 won an electric charge, which accounts for the highest share of. No. 4 is that stylus size server rack 5800 consideration consumes a large electric power to the structure is connected in parallel.
In addition it also requires water-cooled systems and infrastructure, such as cooling towers to keep the performance efficiently cool the heat generated by supercomputers.
In addition, labor costs for keeping and maintaining such personnel to use the super computer repair experts are also constantly consumed.
In the present time technology is much more advanced can build a supercomputer out of a high-performance, lower operating costs in Unit 4 1 year operating expenses. In other countries or research group is the biggest reason why you do not want a super-computer support.
In addition, existing supercomputer was impossible to switch to other applications because they use a custom-made chipset tailored for specific tasks, such as military security. Unit 1 of the National Weather Service, Unit 2 are also these cases.
And some computers that are not discarded are also the museum exhibits, the Cray 1 supercomputer will initially utilizing the unique design was also used as a lounge sofa.
A supercomputer USA to specific examples were sold for $ 45,000 through eBay. SALE supercomputers obsolete, although the actual military operation to have been used in the US military reportedly used in nuclear weapons design and development. Sales at the time the underlying data was provided while both were removed.
The buyer, saying the purchase of a computer for the collection, said the installed next to a tractor on his ranch.
■ some support to the RDA, such as recycled seeking directions
When it was disposed of in the world of supercomputers leads to greater visibility environmental issues such as soy, there are recycling options being discussed. But still, leaving only a necessary part of the whole rather than use super computers to the rest of the steps are destroyed.
Japan Meteorological Agency had also undergone the same disposal procedure, the process was previously part of the dual system to other organs.
Supercomputers will conduct the inquiry took over the national administrations, universities, research institutions targeting two or three times after the hearing and disposal of insoluble shutdown operations before replacement. Abroad it is limited due to enter more like the scale introduced tariffs and local costs.
In the case of Unit 3 s divided into interim, initial minutes, the final minutes, the system took place over three times the insoluble.
Most small-scale interim system after the insoluble eopeotjiman 2015 at the request of any authorities, were previously free of charge got support from the Korea Advanced Institute of Science and Technology R & D KIAS the secondary survey conducted one year later.
Since the early minutes Unit 3 Rural Development under the Academy of Agricultural Sciences 2018, free of charge before the final seven minutes of the rack system we have built nabiseu.
Nabiseu holds more than nine times the existing nongsaengmyeong big data analytics, and application environment based on the enhanced computer system. This presents a state-of-the-art technology-based farming in the agricultural field, such as for assembling 2,000 700 chloroplast genome from rice genome big data based on a short period of time.
Rural Development is pursuing a plan to ensure some degree No.4 finish the mission, based on Unit 3 introduction and utilization technologies. There are also providing big data research building with all necessary facilities for water-cooled supercomputer to reliably operate.
Other agencies departments based on the successful example of the RDA is also expected to consider the introduction of some No.4 ahead disposal.
■ should seek enhanced capabilities forecasters make forecasts improve
Although supercomputer performance is consistently good, public discontent has not diminished.
Still, because they doubt the accuracy of weather forecasting to protect the public life from natural disasters. Rather criticism that the supercomputer invested hundreds of one hundred million won excessively large impact due to this under-performance.
Experts point out that unusual weather phenomenon data analysis problems and excessive work intensity, issues such as forecaster competence lacking due to the rapidly changing due to global warming than a supercomputer.
Super computer because it is more detailed and provides it to actually predicted based on it after detailed analysis of climate information forecasters.
Compared to overseas, Soo - Jin Senator in the National Assembly Environment and Labor Committee, National Audit Korea Meteorological Administration also pointed out that the state did not create the basic conditions for strengthening capacity forecasts.
Senator gangeunmi per definition has also stressed the need to expand the forecasters personnel to increase forecast accuracy.
International has provided the conditions for working for education and research forecasting techniques. UK 4 of renovated 7 Joe is working on a forecast of production and, to a technology research three Joe educational and forecasts, and the Working Group circulated.
Meteorological Bureau forecast predicting a 24-hour shift is the one trillion seven by four renovated 12 hours. Night work - Closed-week tour in 16 days how to circulate the off-duty but has been working overtime continues to lack a garden.
National Weather Service forecasters are currently 128 people but 132 people garden work. Average weekly hours worked in excess of forecasters is the situation in 2021 and worked 9.83 hours a week close to 50 hours. Far resident employee was found to have increased home visits are reduced to once every two weeks at a time in a week the problems in family life and a substantial lag.
Bonnie is also heavily focused on business inevitably reduced capacity compared to overseas lack of time to devote to learning new skills related to weather forecasting.
Noungrae lawmaker said, do not rise to the precipitation presence accuracy is constant, rather it is a problem in the ability of forecasters falls why and in order to enhance the professionalism of the forecasters need to improve the education system and working environment.
Rep. Kim, Sung - Won the force of the people is not different from the general civil service to enhance the professionalism of the forecasters not a job rotation, insisted that the analysis of all of the jurisdiction and create a specialist that can competence and know-how transfer.
